Question

a)identify a, b and c a is the off white layer, b is the pink layer and c is the yellow layer shown in this image
b) what special receptors does layer c contain?
this is an eyeball, sagittal section, showing parts of the eye with arrows a,b and c pointing to layers.

Explanation:

Part A:

• Layer A (off - white) is the sclera (outer protective, fibrous layer of the eye).
• Layer B (pink) is the choroid (vascular layer, provides nutrients to the retina, appears pinkish due to blood vessels).
• Layer C (yellow) is the retina (innermost layer, contains photoreceptors for vision).

Part B:

Layer C (retina) contains two types of special photoreceptor cells: rods (for low - light vision, black - and - white perception) and cones (for color vision and high - acuity vision in bright light).

Answer:

Part A:

A: Sclera; B: Choroid; C: Retina

Part B:

Layer C (Retina) contains rod and cone photoreceptors.
